Reminds me an old dream of mine too...
Of course technology and propellant is changing and things look more feasible today. His rocket looks good but might be underpowered: Comparing this with other rocketry going straight up from the ground and using higher energy fuel, it looks small.
The option to jump with his own parachute ( like Gagarin in 1961) means additional safety without much weight.
